Incremental encoder PG card use instructions
فعالیت
You must choose a PG card when using PG vector control. The function of the PG card includes processing two channels of quadrature encoder signals and supporting the Z signal input for spindle positioning, receiving signals of differential, open collector, and push-pull encoders. Frequency-divided output can be performed for the input encoder signals. The output quantity includes two channels of differential signals. You can choose to output push-pull signals or open collector signals through jumper J1 or J2 according to your actual use. 1.2.2 Terminal and switch description
The incremental encoder PG card has two 2*4P user wiring terminals. See the figure.
PWR and COM1 are for encoder working power output; IA+, IA-, IB+, IB-, IZ+, and IZ- are encoder signal input terminals; OA+, OA-, OB+, OB- are 5V differential frequency-divided signal output terminals, while OA, OB, and COM1 are frequency-divided push-pull signal and open collector signal output terminals (the output signal type is selected by jumper J1 or J2); the PG card does not connect PE to the earth internally, you can ground it during use.
The frequency division coefficient of the incremental encoder PG card is determined by the switch on the card. The switch has 8 bits, and the frequency division coefficient is determined by adding 1 to the binary number that the switch represents. The place labeled with “1” is the low binary bit, and the one labeled with “8” is the high binary bit. When the switch is turned to ON, the bit is valid, indicating “1”; otherwise, the bit indicates “0”. See the following table for frequency division coefficients.

Wiring principles
د تار لګولو احتیاطي تدابیر
- A PG card signal cable and a power cable must be routed separately and disallow parallel routing.
- To avoid interference from encoder signals, use a shielded cable for the PG card signal cable.
- The shield layer of the encoder shield cable should be connected to the earth (such as the PE of VFD), and it must be connected to earth only at one end to avoid signal interference.
- If the PG card uses frequency-divided output when connecting to an external power supply, the voltage باید د 24V څخه کم وي؛ که نه نو د PG کارت به زیانمن شي.
- تاسو کولی شئ د محصول حجم تنظیم کړئtage by adjusting the 12–15V incremental encoder PG card potentiometer (clockwise for voltage increases) according to actual needs, and the force should not be too great when rotating the potentiometer.
Application connection
Input application connection
- Differential output encoder connection
- Open collector output encoder connection
- Push-pull output encoder connection
Note: When the spindle positioning VFD is supported, the Z signal needs to be connected, of which the wiring method is similar to that for the A and B signals.
Output application connection
- PG card frequency-divided differential output connection
- PG card frequency-divided open collector output connection

Note: During open collector output, PWR at J1 and that at J2 are short connected to COA and COB. - PG card frequency-divided push-pull output connection
نوټ:
- During push-pull output, PWR at J1 and that at J2 are short connected to HOA and HOB.

You can choose the output voltage according to your actual use. When transmitting encoder signals over long distances, the output supply voltage can be adjusted using a potentiometer (the voltage adjustment method is the same as that for the incremental encoder card) to extend the wiring distance.
Installation and dimensions of UVW encoder PG card 
یادونه:
- The UVW encoder PG card is installed in the same way and position as the incremental encoder PG card. It corresponds to a double row of 2 x 10 pins.

Terminal and switch description
The UVW encoder PG card has one signal cable interface and seven user terminals, as shown in figure 2-3.
The Sin/Cos encoder PG card has one signal cable terminal and one user terminal, as shown in Figure 2-6.

OA+, OA-, OB+, and OB- are differential output signal terminals (LVDS differential level), while OA, OB, and COM1 are open collector signal output terminals.
نوټ:
- The PG card does not connect PE to the earth internally, you can ground it during use.
- The Sin/Cos encoder PG card and UVW encoder PG card have the similar output signal wiring method as the incremental encoder PG card, but they do not support push-pull output.

When applying either of the UVW PG card, you need to insert the DB15 male connector of the UVW encoder into the DB15 female connector of the PG card. Setting the frequency division coefficient of a UVW encoder PG card is similar to that for an incremental encoder PG card. For details about frequency division coefficients, see Table 1-3.
Note: UVW encoder PG cards can support 5V incremental encoders with differential signal processing, have the similar wiring method with that for incremental encoder PG cards, and mainly use wiring ports include the A, B, Z, PWR, and GND ports on DB15.

Examples
Commissioning procedure for closed-loop vector control on AMs
- Set P0.09=1 to restore to default settings.
- Set P0.03, P0.04 and motor nameplate parameters in group P02.
- Verify whether the encoder is installed and set properly. Slowly rotate the motor or manually oscillate the motor. If the encoder is a resolver, the value of Pb.02 or Pb.04 should increase or decrease uniformly within the range of 0 to 359.9, indicating correct encoder wiring.
Commissioning procedure for closed-loop vector control on SMs|
- Set P0.09=1 to restore to default settings.
- Set P0.00=1 (FVC), set P0.03=3, P0.04, and motor nameplate parameters in group P2.
- Set the encoder parameters P4.00 and P4.01. When the encoder is a resolver-type encoder, set the encoder pulse count value to (resolver pole pair count x 1024). For example, if the pole pair count is 4, set P4.01 to 4096.
- Verify whether the encoder is installed and set properly.
Slowly rotate the motor. If the encoder is a resolver, the value of Pb.02 or Pb.04 should increase or decrease uniformly within the range of 0 to 359.9, indicating correct encoder wiring. - Autotune the initial position of magnetic pole.
Set P0.08 to 1 (rotary autotuning) or 2 (static autotuning), and press the RUN key to run the VFD.- Rotary autotuning (P0.08=1)
Detect the present magnetic pole position when autotuning starts, and then accelerate to XX Hz (depending on the set speed), and then decelerate to stop.
During autotuning process, if a PCE fault occurs, indicating an encoder disconnection or reversed encoder wiring, repeat step (4). If no issues are found, set P4.02 = 1 (opposite to the initial value) and restart autotuning. - Static autotuning
The autotuning process only detects the present pole position without rotating the motor. The magnetic pole position obtained from autotuning is saved to P4.03 automatically.
When using static autotuning, it is recommended to perform the process multiple times. If the identified pole angle varies by more than 30° between attempts, check whether Pb.03 (SM static identification current) is close to 100%. If not, adjust P4.10 (static identification current) and repeat the static autotuning process until Pb.03 is close to 100%.
- Rotary autotuning (P0.08=1)
- Perform closed-loop vector pilot-run.
If current oscillation (noise) occurs, properly adjust the current loop parameters P3.08 and P03.09 (different encoder and motor types require appropriate PI parameters. It is recommended to start with smaller values and gradually increase them until the current oscillation and noise disappear). If speed oscillation occurs, properly adjust the speed loop parameters P3.00 and P3.04. Similarly, start with smaller values and increase gradually until the speed becomes stable. If current oscillation noise occurs during low speed running, adjust P3.02.
Note: You must re-determine P4.02 (encoder direction) and perform magnetic pole position autotuning again if the motor or encoder wires are swapped.
